Control method PWM

This controller designed for solar energy system. It can automatically shutoff and resume to protect against short circuit, overload, over charge , over discharge . With indicators showing the battery charging state, load and kinds of fault instructions. This controller takes parameters according to the battery voltage, current, environment temperature by the computer chip ,after special control calculation, it can realize the discharge rate conform to battery characteristics perfectly . Compensate temperature at very high efficiency and accuracy , used the high efficient PWM charging mode , ensure the battery working in the best state , greatly extend the service life of the battery.

2.Main Characteristics Of Solar Charge Controller

A. Using the single-chip and special software on the basis of expert control system , realized the
Intelligence Optimization SOC control .
B. Using External temperature transmitter to compensate temperature , much precise than
internal temperature transmitter
C. Automatic protect against over charge , over discharge , electronic circuit , overload , these
protections avoid any harm to the component or fuse wire .
D. Take series connection PWM charge as the main circuit , charging efficiency is 3%~6%
higher than non-PWM charging .
E. All the control adopt Industry-specific chip , can running free under any cold , hot , humid
circumstance .
F. Making full use of the advanced power source technology , Greatly improved the effective
power of unit area, much more compact structure.
G. The large diameter, big interval terminals, can install 6 mm2 conducting wire , wire interval
is 9.5 mm, can enhance the isolation and the installation reliability, wires hard to slipping.
